You can select a body or surface from the Structure treeClosed as the target and a plane from the Structure treeClosed as the cutter.

When splitting with a plane passing through the entire body, some cuts may not be desired. Use the Local Slicing option to gain specific control over which cuts are applied.

To split a body by one of its faces

  1. Click the SplitClosed BodyClosed tool from the IntersectClosed ribbon group.

  2. Select the faces or edges you want to use to cut the body.

    Hold Ctrl and click or draw a box to select multiple faces or edges.

    You can create temporary geometry and select it to cut the body.

  3. Mouse over the body to see the regions created by the cut.

  4. (Optional) Click a region to delete it.

    When you are finished deleting regions, select another tool.

    If the selected edges do not completely encircle a portion of a body or surface, no region selection can occur.

     

Select a face with the Select tool, then select the SplitClosed BodyClosed tool to cut the body with the face.

  1. Click the SplitClosed BodyClosed tool in the IntersectClosed group on the DesignClosed tab

  2. Select the body

  3. Check ON the Local Slicing option
